Sigmoid colon is the next most frequent place.

The most common symptoms of colon cancer are bloody stool, bowel movement abnormality (constipation, diarrhea), abdominal pains.

Cancers are mostly small in early stage and they are aware of anal bleeding and are often found in colon cancer screening.

Ascending colon cancer

Selenium levels are lower than normal in colorectal cancer.
